Embodiment Construction
[0037] Such as figure 1 As shown, the present invention discloses an indoor intelligent security method based on WiFi networking, comprising the following steps:
[0038] Step A, for receiving the WiFi signal generated by the signal generating end;
[0039] Step B, analyze and process the received WiFi signal, and judge whether there is an abnormal event and calculate the corresponding alarm level, and execute step C when an abnormal event is detected;
[0040] Step C, sending out an alarm according to the alarm level.
[0041] Described step B comprises:
[0042] Step 1, extracting CSI raw data from the received WiFi signal;
[0043] Step 2, move the rectangular window with a time length of T, and the step size of each window movement is t;
[0044] Step 3, use the current time window to intercept part of the CSI data;
[0045] Step 4, extract the amplitude value and phase value in the CSI data, filter the CSI amplitude value, then calculate the JS divergence of the CSI ...

The invention provides an indoor intelligent security and protection method and system based on WiFi networking, and a medium. The indoor intelligent security and protection method based on WiFi networking includes the steps: A) receiving a WiFi signal generated from a signal generation terminal; B) analyzing and processing the received WiFi signal, determining whether an abnormal event occurs, calculating the corresponding alarm level, and executing the step C when an abnormal event is detected; and C) according to the alarm level, giving an alarm. The indoor intelligent security and protection method and system based on WiFi networking have the advantages of being reasonable in structural setting, being simple to use, being fixed reliably, compared with the prior art. The indoor intelligent security and protection method and system based on WiFi networking can realize indoor security and protection monitoring without dead corners, and can realize combined networking, thus improving the efficiency and being high in practicality.
Description
technical field [0001] The present invention relates to the field of security technology, in particular to an indoor intelligent security method, system and medium based on WiFi networking. Background technique [0002] With the continuous advancement and innovation of technology, remote monitoring systems have gradually become popular. Traditional indoor monitoring methods mainly use cameras or infrared rays to collect data and send it to the alarm host for processing. However, this technology has a lot of limitations, for example, the camera is prone to dead angles, privacy issues exposed under the camera, and the detection range of infrared rays has a certain angle and other shortcomings. Contents of the invention [0003] The present invention provides an indoor intelligent security method based on WiFi networking, comprising the following steps: [0004] Step A, for receiving the WiFi signal generated by the signal generating end; [0005] Step B, analyze and proce...
